Description
Built In Surge Protection Adapter NEMA Socket 7P 347VAC And 480VAC Versions
JL-250F Built in Surge Protection Adapter Socket
The JL-250F is designed for outdoor lamps and installed between the traditional NEMA socket and the light controller. It enables rapid transformation to improve the surge protection capability of NEMA interface lamps. The SPD inside lamps can be replaced by JL-250F, providing more convenient installation, maintenance and replacement while effectively reducing operation and maintenance costs.
The product features built-in surge differential mode + surge common mode protection, significantly improving the light controller's performance in complex electromagnetic interference environments. The combination design of temperature fuse and MOV+GDT prevents heating deterioration caused by MOV aging and over-energy. The center bottom ground hole design provides grounding for the lamp controller and enhances common mode suppression capability.
